Apartment Complex Dumpster Pads: Why the Concrete Under the Dumpster Smells

A dumpster pad smells after the dumpster is emptied because the source of the smell is in the concrete, not in the garbage. Liquid from bags, food waste and rainwater drips out of the container onto the pad, collects in its low spots and soaks in. The truck takes the bags; the liquid on the ground stays where it fell.

Fresh garbage juice is mostly food residue, which bacteria break down. That breakdown is what you smell. On a pad that is wetted again at every pickup and every afternoon storm, the process never stops long enough to dry out.

The liquid under a dumpster comes from three places: bags that split when they are thrown in, food and drink waste that drains to the bottom of the container, and rain that gets in through an open lid and mixes with everything inside. The mixture finds a way out through worn seams, drain plugs, rust holes and the gap at the lid.

The US Environmental Protection Agency's stormwater planning guide notes that dumpsters from contract waste collection agencies are often not appropriately sealed and can leak, and that leaking dumpsters can introduce pollutants into stormwater. A container that leaks onto the pad today leaks onto it again next week.

Concrete holds a smell because it is porous. Liquid that sits on it does not just stay on the surface; it works into the pores and into cracks, joints and the rough patch where the dumpster wheels grind the pad at every pickup. A quick rinse moves the surface layer and leaves the rest.

Older pads are worse. Once the surface breaks down and cracks open, there is more room for the liquid to collect and less chance it will ever drain off.

A smelly dumpster pad is a pest problem first. The same food residue that causes the smell feeds flies, roaches and rats, and a wet, warm pad is where flies lay eggs. Our posts on roaches in trash cans and rats and raccoons around bins explain why food residue draws them in.

For a property manager, the enclosure is also one of the first things residents and prospective tenants walk past. A pad that smells at the gate tells them how the rest of the property is kept.

Some South Florida cities do, in writing. The City of Hollywood's code, for example, says dumpsters and their enclosures must be cleaned after each collection to prevent odors, and that pads and access drives must be repaired when the pavement breaks down. Our Hollywood post quotes the exact sections.

Rules differ from city to city, so the city code where the property sits is the one to check. What does not change is who does the work: the hauler empties the container but does not wash it or the ground under it. That falls to the property.

Hosing the dumpster pad down moves the problem rather than removing it. Plain water from a garden hose does not lift residue out of porous concrete, and the runoff carries it across the parking lot or toward the nearest storm drain. The EPA guide above lists washdown water from waste areas as something to collect, not let run off.

What keeps a pad clean between professional visits:

1. 01Keep the dumpster lid closed, so rain stays out of the container.
2. 02Ask the hauler to repair or swap a container that is visibly leaking.
3. 03Remind residents to tie bags and to put them inside the container, not beside it.
4. 04Sweep up loose litter in the enclosure every week.
5. 05Report cracked or broken pavement on the pad so it can be repaired.

Professional dumpster pad cleaning by The BinFather covers the concrete pad, the enclosure walls and gate area, and the containers that stand on it. Inside buildings we clean trash room floors and the carts in them. We do not work inside chute shafts or on compactor machinery.

How a visit runs:

1. 01We come on collection day, after the truck has emptied the containers.
2. 02We bring our own water and equipment, so nothing is drawn from the property.
3. 03We clean the dumpster or carts inside and out, then the pad and enclosure under and around them.
4. 04The dirty water goes into a collection tank on our truck or trailer — nothing is left on your property.

Details for property managers and boards are on our commercial and dumpster cleaning page.

Dumpster and pad cleaning for an apartment complex starts from $99 for a single container. The price changes with how many containers there are, their size and how often they need doing.

A garden-apartment complex with one front-load dumpster on one pad is a different job from a large community with several enclosures and a trash room in every building, which is why the price follows the job.
